Question

Joaquin wants to make his famous chocolate chip cookies to bring to his friend's birthday party. the original recipe serves 5 people and requires one half of a cup of butter, but he needs it to serve 28 people. how many cups of butter will he need? 1- and one-half cups 1 and four fifths cups 2 and one-half cups 2 and four fifths cups

Answer 1

Joaquin will need 2 and four fifths cups.

What is proportion?

Proportion is an equality between ratios. Two ratios are proportional when the result of dividing the numerator and denominator of the first ratio is equal to the result of dividing the second.

With that said, if Joaquin wants to follows the original recipe he will need to  increase the quantite of butter, but proportionately. Thus:

1/2 of a cup of butter -- serves 5 people

x cup of butter -- serves 28 people

5x = 14

x = 14/5 = 2,8

Therefore, Joaquin will need 2 and four fifths cups.
